Improve :func:`typing.no_type_check`.

Now it does not modify external classes and functions.
We also now correctly mark classmethods as not to be type checked.
bpo-46571: improve `typing.no_type_check` to skip foreign objects (GH-31042) There are several changes: 1. We now don't explicitly check for any base / sub types, because new name check covers it 2. I've also checked that `no_type_check` do not modify foreign functions. It was the same as with `type`s 3. I've also covered `except TypeError` in `no_type_check` with a simple test case, it was not covered at all 4. I also felt like adding `lambda` test is a good idea: because `lambda` is a bit of both in class bodies: a function and an assignment <!-- issue-number: [bpo-46571](https://bugs.python.org/issue46571) --> https://bugs.python.org/issue46571 <!-- /issue-number --> 2022-02-18 21:53:29 -04:00			Improve :func:`typing.no_type_check`.
